Should I Sell a Losing Stock for the Tax Loss?

Updated

Short answer

Selling a stock at a loss turns a paper loss into a tax deduction: it offsets capital gains first, then up to $3,000 a year of other income ($1,500 if married filing separately), and any excess carries forward to later years. The saving is real but limited to your tax rate on the loss, and buying the same stock back within 30 days before or after the sale defers it under the wash sale rule. The tax benefit is a reason to choose when to sell, not a reason to sell a holding you would otherwise keep.

A stock sitting at a loss can feel like dead weight, and selling it for the tax deduction can feel like making the best of a bad decision. Sometimes it is. But the tax benefit is easy to overestimate, and the rules around buying back are easy to trip over. This page sets out what the loss is actually worth, the rules that limit it, and how to separate the tax question from the investment one.

What the loss is worth

A realised loss first offsets realised capital gains. If losses are larger than gains, up to $3,000 of the excess, or $1,500 if married filing separately, offsets ordinary income each year, and the rest carries forward with no expiry for individuals. The saving is the loss multiplied by the tax rate it offsets. A $10,000 loss used against short-term gains taxed at 24% saves $2,400, not $10,000.

The wash sale rule

If you buy the same or a substantially identical security within 30 days before or after the sale, the loss is disallowed for now and added to the cost of the new shares. The window is 61 days in total, and it also applies to purchases in an IRA or by a spouse. Investors who want to stay invested often switch to a similar but not identical fund for the 31 days.

Short-term and long-term losses

A holding sold after more than one year produces a long-term loss, and within a year a short-term one. Losses offset gains of the same type first. Because short-term gains are usually taxed at a higher rate, a short-term loss can be worth more when it offsets them.

Separate the tax from the decision

Selling a loser locks in the loss on that stock. If the reason you bought it still holds, the tax saving alone rarely outweighs the recovery you would give up, and a 30% fall needs a 42.9% rise just to get back to even. If the reason has gone, the tax loss is a bonus on a sale you should judge on its own merits.

Whether selling losers has worked for you is a question your own record can answer. Pure Benchmarks, our own product, compares each sale in a linked account with what the position would be worth had you kept it, and ranks the portfolio against verified investors in the same risk category.

Frequently asked questions

Should I sell a stock at a loss for taxes?

The loss offsets gains and up to $3,000 a year of other income, which is a real but limited saving. Whether to sell depends on whether you would keep the stock without the tax benefit. This page is information for comparison and not a recommendation about any holding.

How much of a stock loss can I deduct?

Losses offset capital gains in full. Beyond that, up to $3,000 a year ($1,500 if married filing separately) offsets other income, and the rest carries forward to future years.

Can I sell a stock at a loss and buy it back?

Not within 30 days before or after the sale, or the wash sale rule defers the loss by adding it to the cost of the new shares.

Is it better to sell a losing stock or hold it?

It depends on whether the reason you bought it still holds. Selling locks in the loss, and recovering from a large loss needs a much larger gain.

Has selling my losing stocks helped my returns?

Compare each sale with what the position would be worth today if you had kept it. Pure Benchmarks, our own product, automates that from a linked account.
